Step-by-step explanation:
the number in the middle
Answer:
S = 2 pi (3) squared + 2 pi (3) (14)
Step-by-step explanation:
The formula for the area of a circle is ...
A = πr²
The cylinder has two circular bases with radius 3 cm, so their combined area in square centimeters is ...
A = 2π(3²) . . . . . . matches a term in the last choice
__
The lateral area of the cylinder is the product of the height and the circumference of the base. That is ...
A = 2πrh
For the given radius and height, the lateral area in square centimeters is ...
A = 2π(3)(14) . . . . . . matches a term in the last choice
__
The total surface area is the sum of the areas of the bases and the lateral area, so is ...
S = 2π(3²) +2π(3)(14) . . . . . matches the last choice
_____
<em>Comment on answer choices</em>
We could choose the correct answer based solely on the area of the bases of the cylinder.
<u>Answers</u>
The function has a domain of all real numbers . True
<em>The cube root of real number is also real. The negative sign is outside he radical so it cannot result to an imaginary number.</em>
The function is a reflection of y =³√x . True
The function is always increasing. False
<em>When getting the cube root of a number the result is alway smaller. So the domain of the function should be decreasing not increasing.</em>
The function has a range of {y|– < y < } . False
The function passes through the point (3, –27) . False
<em>When this values are substituted it the function they don't satisfy it. </em>
